Default Re: lowest oil pressure for engine to survive

there is a mechanical gauge on engine and the old electric gauge ran about the same pressure at the same time frame. think we need to pull oil pan and inspect the pump for wear and plastigauge the mains. the engine is of unknown mileage/lineage, runs smooth, does not over heat more than normal, good compression, good vacuum reading. relief spring is under intake.
